Fig. 6 C illustrates the stretcher accessory 620 for module is extended strip 600.So prolonged The module stretched can be any module type, but most likely display module 610, it can be extended use In easier access or visuality.Stretcher includes carrying out the insertion module of interface with strip 600 622.Modular plug 622 is connected to user module interface adapter 623 via high speed cable 624.Ying Li Solving, user module interface adapter 623 can be various form.Such as, it can be shown simple Adapter.It can also be closed in the box or the cabinet that accept standard module, in order to installs With include described module.This box or cabinet can be integrated into the knot of equipment rack or rack alternatively In structure.
The present invention also allows for mobile module and is each port (either Ethernet, USB etc. in module Deng) retain their network identity (network identity) and connect.Figure 7 illustrates use In the system 700 managing this movement.System 700 is by allowing mixed-media network modules mixed-media (and the net being associated Network information) reorientate together with electronic data processing (EDP) equipment 702, and make it possible to set this For moving to different shelf position (in identical facility or in remote facility) without net Network technical staff the most manually reconfigures network.In the figure 7 with shade instruction EDP 702 and port This movement that module 704 is carried out together.This is carried out in the following manner.Network technician is permissible Use at distribution strip, computer workstation (as directed), server or special equipment (all These have TCP/IP(or other suitable Data Transport Protocol between which, but preferred embodiment It is TCP/IP) network connection) go up the network configuration management device (NCM) 708 run to configure strip 706 networks realized.This can include using external networking component, uses the most in the standard fashion From the router of other supplier and switch, the gateway such as arriving other network or VLAN, etc.. This be such as be frequently found in TCP/IP (and other Data Transport Protocol) environment, multi-provider real The existing standard network function in network.
NCM software interface can be Command Line Interface, web interface, traditional GUI or its any combination. The topology of network that network technician can use NCM 708 to define by distribution strip to be formed, road By and address space.This includes by the main frame of the network of topology definition and/or network subelement (such as TCP/IP subnet or VLAN) between any restriction of connection, such as packet filtering, business game system Determine or be used for controlling between two or more main frame and/or network (or subelement of network) Other router connected or firewall method.It also includes management address space, such as, specifically Host address to be connected to the network port equipment fixed direction allocation with communicate.
Undesirably basis at each strip, each module or each port can also carry out bandwidth Limit and packet shapes.NCM 708 can be replicated for the availability increased so that NCM function is always Can use, or its function can computer workstation (or server) and embed equipment between, And or be distributed between distribution strip 706 self.Each NCM 708 (includes its all of duplication Product) control the management domain of set as the network controlled by NCM 708, no matter their physical address is such as What.Only requirement is that all of assembly is connected by TCP/IP or another suitable Data Transport Protocol Connect.
It addition, technical staff can use NCM 708 to be provided for management and control in which distribution strip Can there is and connect the rule of which network subelement.These rules such as can be in the logic of network End in structure (topological sum address space etc.) and network wiring strip 706 and strip 706 In the physical location (including the module slot position in distribution strip) of mouth die block 704 any one or It is performed both on operation.As such, it is possible to expectation moves to another one when port module 704 from a position When putting (this includes moving the equipment enclosure module useful, in single strip 706 of segmentation), Forbid that any or all of the port in port module 704 works, because it violates in NCM 708 The defined connection strategy arranged.This can be carried out when port module is inserted into new position, and Error message can be shown at this moment.
Each of distribution strip 706 can have one group of unique identifier.Network wiring strip Virtual ID (NDSVID) is distributed by NCM 708 and is stored in their firmware.Additionally, port mould Block each can have and be allocated: come one group of identification port module as entirety and uniquely identify Symbol, i.e. port module virtual ID (PMVID)；And the independent port of each port being separately identified in module Virtual ID (IPVID).NDSVID is distributed to distribution strip 706 by NCM 708, and is stored in In their firmware 710.PMVID and IPVID is distributed to port module 704 by NCM 708 and deposits Storage is in their firmware 712.
When distribution strip 706 is inserted in any network first, the processor 716 of NCM 708 to Its distribution NDSVID and each module 704 in strip 706 distribute PMVID and to each end Mouth distribution IPVID.When port module 704 is first activated, either in joining of being first activated In line socket bar 706, or by being inserted into first, distribution strip 706 is first activated, NCM 708 is by the PMVID being used for module 704 for its distribution and each end being used in module 704 The IPVID of mouth.When module 704 is inserted into strip 706 first or strip 706 is energized, PMVID and each IPVID is transmitted to strip 706.Then they be transmitted to network by strip 706 NCM 708(one part may local in strip 706 realize), and NCM 708 subsequently may be used With about the institute on each port allowed in the module 704 just inserted or the strip 706 being initially powered Network completely connects, restricted network connects or do not has to have all of the port in module 704 to have Network connects and tells what strip 706 does.Be appreciated that this for encrypt this information storage and Transmission is so that making network be properly protected will be useful, and expects generally to protect reality in this way Existing.
NCM 708 also preserves the information of " mapping graph " for defining logic network in memorizer 714, It can include the distribution of the topology of logic network, address space and connection strategy, such as, be enough to define this net The information of network.With each port module on these one or more NCM 708 being stored in management domain On 704, and " mapping graph " is changed, all to the strip 706 managed by NCM 708 every time In all modules 704 on copy be updated so that they are all identical.It is appreciated that Store " mapping graph " on each port module and allow to the copy reconstructed network from " mapping graph ", and And this feature is probably useful.NCM 708 can carry out Version Control to the copy of " mapping graph ", Change to network can be reversed and previous network version can be recovered." mapping graph " also may be used To comprise each element of network, NCM 708 and distribution strip 706 and port module 704 alternatively Physical location data.If connection strategy comprises the rule relevant to position, this is useful.Will reason Solving, positional information and other network information can be stored separately by NCM 708 rather than be stored in dress Put in firmware 710 and/or 712, in order to be then reported to NCM 708.This mapping graph is digitally stored And there is unique digital signature.
Alternative implementation and can use the subset of " mapping graph " or can be applicable to the network equipment Network identity.The network identity of each single port is stored in its port module.In this realization side In formula, for the specific network information of each port on port module, (network characterization, network connect plan Summary, the network address, subnet mask, gateway address, other routing iinformation, etc.) be all stored in The network information in this module.When mobile module, this network information is transmitted to distribution strip, its Send this network information to NCM.With application network connection strategy, then NCM can determine what network is even Connect and this module is awarded and instructs network wiring strip (and other network equipment needed any) Realize it.
These elements make it possible to from first strip module moved to second strip, second Strip then reconfigure self to provide required network configuration so that each on port module Port can have desired network function.This feature may be used for multiple Data Transport Protocol (TCP/IP, Fiber channel, token ring and other) and multiple link layer protocol (Ethernet, FDDI, HDLC and Other) and other agreement (USB, RS-232, etc.).It shall yet further be noted that it can utilize different things Reason media operation and this physical medium can via GBIC or with each port in port module Other means that network identity is unrelated and exchange.
Fig. 8 shows the process 800 that management module moves.Assuming that module has been activated at least one times, And there is the network identity distributing to one or more port thereon, NDSVID, PMVID, one or Multiple IPVID are the most either manually or automatically arranged 802 by NCM by following strategy setting, Described strategy setting is included in the default policy that can use when module is inserted into, and (one of them can be not Enabling any network to connect, generate and report to the police and wait that operator intervenes, this is useful to high security context ).
When mobile module subsequently, it is possible to achieve following preferably sequence of events.This module be inserted into and Transmit (at least one) IPVID of 804 its PMVID and its all of definition and " mapping graph " thereof Copy is to distribution strip.Distribution strip forwards 806 all these information to NCM(and can be in order to These ID are supplemented, such as to identify new module position) by its NDSVID or other network information. This NCM obtains the digital signature of the EM equipment module copy of " mapping graph ", and by itself and " mapping graph " The digital signature of current copy compare 808, to check whether they mate 810.Should be understood that When " mapping graph " is the subset defining the information needed for network, whole network of network can be organized " to reflect Penetrate figure " so that this entity in network " mapping graph " is each also have can be searched respective label Name.If they do not mate, then then NCM will compare the digital signature of reception and " mapping graph " of accreditation List, and find coupling." mapping graphs " of these accreditations can manage with other NCM other Network is correlated with, and other NCM described has how defined in local NCM, guidance are treated from those The connection strategy of the module of network.This can include creating and route new network entity (such as VLAN), The network entity (such as VLAN) that remaps is to new address, and retains or redistribute main frame ground Location.NCM can also obtain from other source, the network information that such as identifies new position.If looked for not To coupling, default strategy can be applied, such as, stop and connect or allow restricted connection.Also may be used To take other action, such as generate and report to the police or display error message.Upon finding the match, result is Set up between new module and network (and its any network that can arrive at) according to connection strategy 812 Desired connection.When in the port of the activation during equipment is inserted into port module, also will realize This strategy may need other actions all taked, and such as particular host address is connected to the network port Equipment fixed direction allocation with communicate and/or set up expectation network connect need other internet message (all Such as subnet mask, default gateway etc.) fixed direction allocation with communicate.NCM then can the most more All copies of new 814 " mapping graphs ".
The security function added can also be realized alternatively.This is to confirm network before granting network connects The mark of equipment.This can be carried out as follows.Unique device id (DID) configuration can be utilized to be moved Each EDP equipment.This can be carried out in many ways.In a preferred method, connect first at this equipment The mark of (or replacement) this equipment, when receiving network, is set.The group of known DID can be that network " reflects Penetrate figure " part, and be equivalent to each IPID internet message the network information can also with " reflect Penetrate figure " in each DID be associated.Adaptive can arrange DID makes it be safe and can verify that Existing method (such as 802.1x), or can be this function create autotelic structure (purpose Built) application protocol.After distribution strip, it is configured with port module and each port, but To enable before network connects, the network port of each activation (each have be inserted into and be energized The network equipment, this generally can be sensed by the port at link layer) inquiry connect device with obtain Its DID, is then sent to distribution strip by DID, and distribution strip is continued to be sent to NCM. Then NCM compares the list of the local network of DID and accreditation or telecommunication network DID, and (it can be always Extract in " mapping graph " of telecommunication network NCM) and selectively allow for meeting the connection plan of definition Desired network slightly connects (completely, restricted or do not have).As a part for this process, NCM DID can be verified before connecting ratifying any network.If DID, NCM that this equipment does not define before One or request is distributed according to default strategy (it can be maked decision based on all available information) Operator intervenes what decides to do.DID is then added to " mapping graph ", is updated, and will DID stores on said device.
As it will be appreciated, the present invention allows electronic data processing (EDP) equipment in data center or Move between data center, move without network technician and be just moved to the specific of diverse location The network identity of equipment or reconfigure network so that the service of work.Although it will be appreciated that network is excellent Selecting embodiment is the network wiring strip using the perpendicular shape factor with port module, but other Form factor (network switch that the most traditional frame is installed) can also be designed to accept described mould Block and to carry out work with perpendicular network distribution strip exact same way.
Another embodiment of the present invention is as follows.Can use have integrated or modular (but lack The feature of few above-mentioned port module) the perpendicular shape factor network wiring strip of the network port or routine The network equipment installed of frame make the EDP equipment can be as follows with similar with the method described before Mode and move between the network port.As previously described, each EDP equipment of network it is connected to Unique device id (DID) that is safe and that can verify that can be configured with.Can be by " mapping graph " The current pair of (or only there is the information specific to this equipment and the subset of tactful " mapping graph ") Originally it is placed on each EDP equipment being configured for DID.Depend on type and the assembly thereof of EDP equipment Option, this can be stored in firmware or be stored in suitable storage device (such as hard drive Device) on.When moving EDP equipment in a network, use identical basic skills by the network of this equipment Mark moves to new port.This is carried out as follows.
EDP equipment is inserted into, and transmits the copy of its DID and " mapping graph " to the network equipment.Net All these information are transmitted to NCM by network equipment.Then NCM can verify DID before further processing. NCM obtains the digital signature of " mapping graph " from EDP equipment, and by its current with " mapping graph " The digital signature of copy compares to check whether they mate.If they do not mate, NCM is then The digital signature of its reception and the list of " mapping graph " of accreditation will be compared, and find coupling.These " mapping graph " of accreditation is other network managed by other NCM, and other NCM described has in this locality NCM has definition, instruct and how to treat the connection strategy of the EDP equipment from those networks.NCM Then will search the DID of EDP equipment in Local or Remote network " mapping graph " and determine that EDP sets Standby being recognized is attached.If it is, it will instruct the network equipment company according to definition Connect strategy to ratify and realize network to connect.This can include creating and routeing new network entity (such as VLAN) network entity (such as VLAN) that, remaps to new address and retains or redistributes Host address.The function occurred is based on connection strategy and sets up new EDP equipment and network (and it can Any network to arrive at) between desired connection.Can also carry out realizing this strategy may need to adopt Other actions all taken, such as particular host address to the fixed direction allocation of EDP equipment with communicate and/ Or set up other internet message (such as subnet mask, default gateway etc.) that the connection of desired network needs Fixed direction allocation with communicate.It shall yet further be noted that the EDP equipment for having multiple network port, will be often The secondary network port repeats this sequence of events when being inserted into or be mobile.
